Trenches in Tyrone

Spirit's right front wheel failure on its way up McCool Hill to find a winter haven resulted in the rover having to turn around and go back to the hill to find another place to survive winter. The traces on the left correspond to the path of the rover up McCool, and those on the right are from the seized wheel digging a trench into the ground. This area is called "Tyrone," imaged on sol 1099 (February 5, 2007).
